Found that if you get the mystery novel from the library, the 'Jacob myster novel' event repeats every time you go to the flowershop.
(Mac version) I have no clue whether the same thing happens in the other versions.

Hello, yes was fixed in the version 1.1 that I uploaded a few hours ago, please redownload the demo and the problem should be gone (you can see the game version number in the top-left corner of the main menu)
